FragmentViews-class | R Documentation |
The FragmentViews class is a basic container for storing a set of views (start/end locations) on the same peptides/protein sequence. Additionally it keeps information about mass, type and charge of the fragments.

In general it is not necessary to call the constructor manually. See
